Surgeons had to remove part of a 10-year-old boy's foot after he was struck by a train about 2:20 p.m. in south Stockton, loved ones said. Authorities said the boy was injured while trying to jump aboard a moving train near South Stanislaus and East Taylor streets.

The boy suffered severe trauma to his foot, authorities said. He was taken to a hospital, where he underwent surgery, received a blood transfusion and had part of his foot amputated, according to his mother's boyfriend.

At 5:09 p.m., a 7-year-old boy was riding a bicycle in the 3700 block of Hatchers Circle in Lincoln Village West when he was struck by a car, authorities said. The boy was taken to Mable Barron Elementary School on Cumberland Place, where a helicopter landed to fly the boy to the University of California, Davis, Medical Center in Sacramento for treatment of a broken femur, authorities said.
